Answer:
The answer is D.
Step-by-step explanation:
Well since there are 4 values calculated then 2 would be above the mean because plus the 2 values above the mean. I don't know if it makes since though.
Answer:
A - (2a+0)/2 ; (2b+0)/2 = ( a , b )
B - (-2a+0)/2 ; (2b+0)/2 = ( - a, b )
C - (-2a+0)/2 ; ( -2b+0)/2 = ( - a, - b )
D - (2 a+0)/2 ; (-2b+0)/2 = ( a , - b )
Step-by-step explanation:
Answer:
9/4
Step-by-step explanation:
(-3/2)^2=9/4
Answer:
3x - 14
Step-by-step explanation:
Perimeter = 2(length+width)
= 2[(½X-7) + (x)]
= 2[½x + x - 7]
= 2[1.5x - 7]
= 3x - 14
Answer:
The correct answer is x > 2.
Step-by-step explanation:
An inequality compares two quantities unlike an equality. An inequality is written with either a greater than ( > ) or lower than ( < ) or greater than equal to ( 
) or less than equal to ( 
) signs. We solve the above given inequality to find the solutions of the unknown x.
Firstly we change the right hand side quantity to fraction.
We then transfer the - 
to the right hand side and add them. The inequality sign does not change as we are simply adding or subtracting terms from both the ends.
Finally we divide both sides with 
to get the required solution. The inequality sign does not change as we are multiplying both the ends with a positive quantity.
This gives us the answer as x > 2.
